Title: Low-pressure mercury vapor electric discharge lamp and lighting system
Inventor: YORIFUJI TAKASHI
IPC: F21V19/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To quantitatively fill mercury and concurrently improve a lamp characteristic such as a starting characteristic and a lumen maintenance factor by applying the constitution that electrodes as a pair are laid so as to be faced to each other at a prescribed electric discharge gap, one electrode is formed to have a mercury discharge body structure without a getter, and the other electrode is formed to have only a getter without a mercury discharge body structure. SOLUTION: A low-pressure mercury vapor electric discharge lamp L1 is formed to have a mercury discharge body structure 6 and a getter 7 different from each other in acting temperature laid on separated mounts 2A and 2B, and not on the same mounts 2A and 2B, so as to perform mercury discharge and activation separately. The prescribed amount of mercury Hg is thereby discharged. Also, impurity gases once adsorbed to the getter 7 are not again released and the extent of the deterioration of a lamp characteristic such as a starting voltage rise and a lumen maintenance factor drop is lowered, compared with the conventional case. In this case, the getter 7 may be activated, using the heat of a filament electrode 5B capable of generating heat upon receipt of power, without any a high-frequency heating process.

Abstract: PURPOSE:To enable to increase a protective current as well as to obtain a low input capacity element by a method wherein a DSA type FET, consisting of a double- diffusion region and a reverse conductive region, are formed on a low density substrate and the reverse conductive region to be provided on the substrate is connected to the gate of a circuit element. CONSTITUTION:For example, the pattern of an oxide film 33 and a nitriding film 23, with which the double-diffusion region is demarcated, is formed on an N<-> substrate 13 and an N region 43 is provided using an oxide film mask 53. Then, after P regions 63 and 73 have been formed, a selective oxide layer 83 is provided using the nitriding film as a mask in such manner that the junction will be formed directly below the oxide film 33. Then, the nitriding film is removed, a gate electrode 93 contacting a region 63 is provided and grounded (to be connected to the source of FET on the circuit), and the region 73 is connected to the input gate of the circuit. As the junction capacity of the region 73 is small, input capacity can be reduced and a large current can be applied in between regions 43 and 63, thereby enabling to have the diode suitably used for a protective element.
